I added a new custom field of type Tempo Account.
I'm doing a bulk update now on 25 cases to set the value of this field. When I select the new value and confirm the bulk update, Jira tells my it's going to set that field to blank, no mater what I select as the default value.
Here I select the new value:

edit: Also the checkbox to disable sending an email isn't working. It always says it will send an email even if I uncheck it. Other fields seem to work fine.
Any idea what's going on here or how I bulk update these cases. I have more than 25, but am just starting with these.
